According to several sources, Dolan was furious about the 22-story, 21,375 square-foot billboard and called league officials to complain, a tactic he repeated last year after Prokhorov referred to him as “that little man” in a New York Magazine article.

By all accounts it was nothing personal for Prokhorov—just good business. But after hearing from Dolan one too many times, Stern summoned both owners for a meeting to work things out. The Post's sources say it was "cordial and friendly," and the interborough sniping seems to have tailed off. In fact, the Knicks and Nets are expected to co-host the 2015 all-star weekend.
